There are separate parts for the central transmission hump also with tread plate pattern included as well as the gearshift "box" and replacement hand brake made up of twp parts and wire cable plus the driver's brake and clutch pedals. The seat mountings are also in brass with additional smaller brackets and seat levers with all this adding some nice details to the kit floor.

This set can be used to correct the undersized transmission hump in the initial Dragon 251 Ausf.D kits or simply to add additional detail to the later kits as well.
